drm/hisilicon/kirin: Set .dumb_create to drm_gem_cma_dumb_create()

The kirin drivers uses drm_gem_cma_dumb_create_internal() for its
.dumb_create implementation. The function is meant for internal use
only by drivers that require additional buffer setup.

Kirin does not do an additional setup, so convert it over to
drm_gem_cma_dumb_create().
